Genesis 18:3-5

3“My lord,” said Abraham, “if I have found favor in your sight, please do not pass your servant by. 4Let a little water be brought, that you may wash your feet and rest yourselves under the tree. 5And I will bring a bit of bread so that you may refresh yourselves. This is why you have passed your servant’s way. After that, you may continue on your way.”

“Yes,” they replied, “you may do as you have said.”
